Why didn't you tag me?!: Social exclusion from Instagram posts hurts, especially those with a high need to belong

In recent years, researchers of various disciplines have developed many theories to understand the radicalization process. One key factor that may promote radicalization is social exclusion, the state of being kept apart from others. Indeed, experimental studies have provided initial evidence for a relation between exclusion and radicalism. The current review outlines and builds upon these research programs, arguing that social exclusion has been shown (a) to increase the willingness to fight-and-die, (b) to promote the approval for extreme, even violent, political parties and actions, and (c) to push the willingness to engage in illegal and violent action for a political cause. We close with an agenda for future research and critically discuss implications of this work for social policy. 

How social exclusion makes radicalism flourish: A review of empirical evidence

Previous research has confirmed the harmful effects of cyber-ostracism on adolescents. However, research that has investigated the effect of cyber-ostracism on adolescents’ psychological well-being and the underlying mechanisms of this influence remains scarce. Using a sample of 421 Chinese adolescents, this study examined the short-term effect of cyber-ostracism on adolescents’ psychological well-being, along with the mediating effect of rumination. Mindfulness is considered as a moderator influencing this underlying mechanism. Questionnaires regarding cyber-ostracism, rumination, and mindfulness were administered at the beginning of the spring semester. Psychological well-being was assessed three months later. The study found that cyber-ostracism significantly and negatively predicted adolescents’ psychological well-being. As shown by the mediation analysis, rumination partly mediated the effect of cyber-ostracism on adolescents’ psychological well-being. Moderated mediation analysis indicated that mindfulness played a moderating role in the relationship between cyber-ostracism and adolescents’ psychological well-being as well as the relationship between cyber-ostracism and rumination. Specifically, mindfulness would decrease the negative impact of cyber-ostracism on adolescents’ psychological well-being. This study uncovers the short-term effect of cyber-ostracism on adolescents’ psychological well-being and accentuates the underlying mechanisms of this effect, which has substantial implications for interventions and practices to reduce the detrimental effects of cyber-ostracism among adolescents.
